The essentials.

Typical faults by engine

The period and mileage are those mentioned by each sheet's sources. They are not a maintenance interval and do not predict that any particular car will fail.

    Period mentioned
    2009–2014
    Mileage mentioned
    What the sheet says: The guide recommends replacing the chain at around 100,000 km to stop it breaking. The fuel filter often clogs and the clutch wears out before 60,000 km when towing. On the automatic, changing and flushing the oil helps.

    Applies if: Same R-family CRDi diesel (D4HA/D4HB) as the Sorento II, where the German guide documents the chain and fuel filter.

According to the data we have, all its engines have the same number of documented faults.

We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.

Official recalls: ask before you pay

A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.

  1. Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
  2. Ask an official Kia dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
  3. Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

0 of 4 checked

Fuel system

  • Look out for: A diesel smell or stains in the engine bay; in the worst case, fire.

    Ask them to check: Check the campaign by VIN; with a diesel smell, do not drive.

Steering

  • Look out for: When turning the wheel one way and the other there is a scraping or rumbling noise from the steering. The steering does not get heavier.

    Ask them to check: Ask a Kia dealer to check where the noise comes from and, if it is this bearing, to replace it with the kit from bulletin CHA122 (only the bearing is replaced, not the column).

Injection / turbo

  • Look out for: Loss of power, higher consumption, hesitation or rough idle, usually at high mileage.

    Ask them to check: Read misfire and fuel-trim codes; inspect the injectors and valves with a borescope; clean the intake if there are deposits.

Valve timing

  • Look out for: Chain noise at high mileage, hesitation or loss of power from a clogged fuel filter, turbo whistle and a worn clutch when towing; on automatics, harsh shifts.

    Ask them to check: Listen to the chain when cold, change the fuel filter on time and test the clutch under load; on automatics, check the gearbox oil.
